Manual Stages - Overview
Guide: Linear Ball
Clamp
Feed: Micrometer Head (Resolution 0.01mm)
QWhat is a Stage? Stages are mechanical unit products composed
of Guides, Feed mechanisms, and Clamps. Since they can easily
adjust object positions for inspections,
machining, and assembly fixtures. A single unit would be used as
an X-Axis, and two units can be combined as an XY-Axis stage. Use a
Z-Axis for height adjustments.

Structure Sliding male/female trapezoid grooves facilitate the
guiding.
Caged cylindrical rollers are alternately crossed, and placed
between two grooved rails.The rolling motion of the rollers
facilitates the guiding.
Steel balls are aligned in gothic arch grooves machined on the
body of stage.The rolling motion of the rollers facilitates the
guiding.

ENotes on Clamps The standard clamps for the stages work on
frictional forces generated when screws are tightened by turning
the knobs and levers. Applied loads exceeding the friction
of the clamp mechanical forces can displace the stages. Please
devise proper countermeasures to prevent the stage surfaces from
being displaced in actual applications. MISUMI offers the following
clamp reinforcement measures. • Selecting the Reinforced Clamp Type
Stages (Slit Type Clamp) • Changing the clamp type when available
as "Alterations" (Opposed Clamp, Disc Clamp)

Features
Clamp plate is pressed against the side of the stage by a clamp
screw. It is the most economical and standard holding method.
The stage is immobilized by clamping a disc applying no load on
the stage surface. The advantage is that position displacement can
be prevented.
The carriage is braced by a bolt from the other side of the
micrometer head. The bolt is secured with a nut for vibration
resistance and strong holding capacity.
The feed knob shaft is clamped directly. Compared to the
conventional model, larger retaining force can be obtained. Drift
can be prevented by using it in combination with conventional
standard clamp.
The final tightening action o f the c lamp sc rew i s managed
with a lever for easy operation.
Technical Information
QAbout Load Capacity Load Capacity It is a force that the stage
can withstand with the CG of the load is the stage center. The unit
is in (N). If the stage is operated at beyond this load capacity,
it may no longer operate smoothly. For the load capacities in
horizontal orientation, see [Horizontal] values, and see [Vertical]
values for the vertically oriented stages. Please be advised that
vertically oriented or inverted stages may not always meet the
catalog accuracy values.
Allowable Moment Load It indicates loads the stage can withstand
when the CG of the load is located away from the stage center. The
unit is in (N • m). When CG of the workpiece is located away from
the center of the stage (=Overhung), the allowable moment load
values will need to be taken in consideration along with the Load
Capacity. Products high in this value is defined as [High
Rigidity].
QAbout Accuracy StandardsDefinition of Straightness
Straightness is a value represented by a maximum difference
between an ideal straight line of travel and the actual travel of a
top plate over the entire stroke range of the stage. It is the max.
deviation in horizontal or vertical direction in relation to the
ideal straight axis.
• Straightness (Vertical) Measurement A stage is fully stroked
with a dial indicator placed and a vertical displacement is
measured.
Definition of Pitching / Yawing / RollingThese indicate the
amounts of top plate inclinations during linear motion.To direction
of travelingLeaning forward and back : PitchingRotation in a
horizontal plane : YawingLeaning right and left : Rolling
Allowable Moment Capacity (see Overview page) and Moment
Rigidity (carriage attitude in angles against these forces) are
used to represent the stage's rigidness.

QAbout Resolutions There are 3 ways of position reading options:
Scale Plates, Vernier Scale and Micrometer Heads.These position
indicating options can be used as references for
applications requiring positional repeatability.
1 The scale B value is read at the 0 position of the sub-
scale A in 1mm resolution. (30mm in the right figure)2 While
looking at A scale, read the graduation C
aligning the B scale as 0.1mm resolution. (0.6mm in the right
figure)3 A sum of 1 and 2 is the value. (30.6mm in the right
figure)
E�Although the micrometer head stroke will be expressed ±3.25mm
and ±6.5mm, the scale starts as 0 (zero) at the left farthest
end.
For the case of ±6.5mm stroke, the relationship of the scale and
the stroke would be as shown below. • When the scale reads 0
(zero): Stroke [-6.5mm] • When the scale reads 6.5mm: Stroke [0
(zero)] • When the scale reads 13mm: Stroke [+6.5mm]
1 Read where the position of end face of the thimble is
located on the scale of sleeve by 0.5mm resolution. (11.5mm in
the right figure)
2 Read a value of the thimble on the position where the base
line of sleeve coincides with the scale line of the thimble.
(0.36mm in the right figure)3 The total value of 1 and 2 is the
current position of
the stage. (11.86mm in the right figure)

Q�About Stroke (move distance) descriptions. The dimensions
shown in the drawings are for tables at 0mm positions. The
dimensions shown in ( ) mean that they would change as the stroke
changes. Below diagram
[XWG60] as an example, the stroke is ±21mm (42mm) where the
table moves 21mm to the right and 21mm to the left, as the position
in the diagram as the center. In the case of the drawing [ZLFG40]
below, the stroke is ±5mm (10mm), and the dimension indicating the
stage height (41) means it changes between 36mm (-5mm) and 46mm
(+5mm).
